My invention relates to an address printing machine with a blank feedingmechanism. The mechanism comprises a blank holder which is fed step bystep in the longitudinal direction of the blank when an address has beentwice printed on the blank from a given printing plate and is' the frameof the blank feeding mechanism, is

operatively connected to a one-armed lever, or rocker, which isfulcrumed at one end on the support for the blank holder and whose otherend is connected to the blank holder by a short link. The blank holderis guided by a pair of parallel links which are fulcrumed on thesupport.

In order to combine with the lateral shifting "movement thus imparted tothe blank holder, an adjustable longitudinal movement of the holder, ina preferred embodiment of my invention the parallel links are fulcrumedon an anchoring 'plate or slide which is arranged to be shifted at rightangles to the feeding movement on the support, and can be held on thesupport in any desired position.

In the accompanying drawings an address printing machine equipped withthe blank feeding mechanism embodying my invention is illustrated'by wayof example.

In the drawings Fig. l is an elevation, for the major part in section onthe line II in Fig. 2, showing a portion of'the address printing machineand the blank feeding mechanismcwith its blank holder ready for thefirst impression from a given printing plate.

Fig. 2 is a plan view of Fig. 1, partly broken away. I

Fig. 3 is a detail plan view, drawn to a larger scale and showing theblank holder in the same position as in Fig. 2, and the anchoring plateon which the parallel links are fulcrumed, in its central position.

Fig. 4 is a section on the line 'IV-IV in Fig. 3.

Fig. 5 is a plan view corresponding to Fig. 2'

but showing the blank holder ready forthe second impression.

Fig. 6 is-a-plan-view corresponding toFig. 3

'on a shaft 33 below the table.

"is inserted the blank 95. the support 33 engages in teeth at the upperend marked "with "the index' (Cl..2715 l)- "but showing the anchoringplate in its final position atthe right, as viewed in the feedingdirection.

Referring now to the drawings, and first to "Figs. 1 and 2, a printinghead 2 is pivotally 5 mounted on the table of the machine at 3. The

'mechanism for oscillating the printing head and for feeding printingplates to a printing station has not been illustrated as it is not aparty of the present invention.

10 The printing head is equipped with a pin engaging in a slot at theupper end of an arm as An arm 36 extends downwardly from the shaft 355and the left-hand ends of connecting rods 39 and 4B are pivotallyconnected to the arm 36.

The right-hand endof the rod 39 is pivotally connected to a cross headwhich is mounted to slide on a rod 6! and to be fixed thereto by a setscrew. The rod ll is the tail end of a feeding sector A l on a shaft &3.The sector 44 meshes with a vertical rack All which is mounted to slide"in the frame it of the feeding mechanism and,

in manner per se known in address printing machines, feeds the blankholder stepwise in the direction of the arrow '35 in Fig. 1 when thesector *M is-turned clockwise, that is, against the arrow i 35.

Mounted to slide on the frame it is a support it for the blank holder.By means which will be described, the support holds and guides a clampI25 at the rear end of the blank holder in which A pawl, not shown, on

of the rack 47? when the rack moves to the right in the feedingdirection (it, carrying the support it in the same direction. In theopposite direction, the pawl is idle.

The mechanism for shifting the blank holder,

' with its clamp I26, laterally, that is, transversely 40 a pinion H2,and those lit" at the right mesh with a pinion H2. The two pinions andthe elements connected thereto are exactly alike and so only'the .pinionH2 will be described, the corresponding elements for the pinion H2 beingThe shaft H3 of the pinion H2 is mounted to rotate in a suitable bearingof the frame 46. A crank H4 is placed on a flange H3 of the shaft H3with a slot H5 so that the effective length of the crank can be varied.At its free end the crank I I4 is pivotally connected to a slide blockH6 in a slot H1 in a rod H8. The rod H8 has rollers H9 at both endswhich engage in grooves in the tranverse stays of the frame 46 and itwill appear that the rod H8 is shifted to and fro laterally as thepinions H2 and H2 rotate.

A rocker I22 is fulcrumed below the support 48 at I2 3, as best seen inFig. 4. A U-shaped bracket I21! is placed on the rod H8 and the rocker22 engages a pin I2I on the rocker. A short link I2! connects the freeend of the rocker to a pin E2? on the blank holder. The blank holder, asbest seen in Figs. 3 and 6, comprises the clamp I26 already referred toand an angle member I25, I28. The clamp I26 is adjustably mounted on thearm I25 of the angle member by means here shown as a wing nut. A baseplate I38 extends to the left from the lower side of the support 43 asfar as below the clamp I26 and the angle member is equipped with a blockI39, preferably of hard rubber, which slides on the base plate E33 asthe blank holder moves. A pair of parallel links I29 and I29 arepivotally connected to the ends of the arm I28 of the angle member withtheir left-hand ends, and their right-hand ends are fulcrumed on ananchoring plate I3 This plate is mounted to slide in a groove I3I in thesupport 48 and held in any desired position in the groove by a bolt I32and a wing nut I33, as best seen in Fig. 4.

A cover I34 is placed on top of the support 48 and secured by screws I40engaging in threaded holes I35 in the support. An index I36 is placed onthe bolt I32 below the wing nut I33 for cooperation with a graduationI31 on the cover I34.

The operation of the blank feeding mechanism will now be described. Theparts are supposed to be in the position illustrated in Figs. 1 and 2,in which the first impression is made of a printing plate which has justarrived at the printing station. The slot at the upper end of the arm 34is so curved that the arm is not influenced when the printing head 2descends for making the first impression on the blank 95 at the printingstation. When the impression has been made and the printing head 2 movesupwards into its initial position, the arm 34 is turned anti-clockwise,as indicated by the arrow in Fig. 1, causing partial rotation of theshaft 33 and a corresponding movement of the arm 36 in the direction ofits arrow. This causes both sectors 44 and III] to be turned in thedirection of the arrow I45 through the connecting rods 39 and 40.Movement of the feeding sector 44 in this direction is idle, that is,does not feed the mechanism in the direction of the arrow 45, but theshifting sector HE- carries its rack III to the left in the direction ofthe arrow I46 in Fig. 2. This causes rotation of the pinions H2 and I I2in clockwise direction, as indicated by the arrows in Fig. 2, andlateral shifting of the rod H8 in the direction of the arrow 5'! in Fig.2 and into the position illustrated in Fig. 5. The rod, through themeans described, moves the rocker I22 in to the position illustrated inFig. 5, and throws the blank holder into that position in which theblank 95 is ready for the second impression. In other words, the blankis shifted transversely to the feeding direction. By the parallel linksI29,

I29 the angle member I25, I28 is shifted in parallel relation to itself.When the blank 95 has arrived in the position illustrated in Fig. 5, andthe printing head 2 descends, the second impression of the printingplate at the printing station is made on the blank below the firstimpression.

When this operation has been performed, a fresh printing plate is movedto the printing station by means known in this art while the printinghead 2 ascends. The ascending printing head returns the arm 34 into theposition illustrated in Fig. l and this causes rotation of the twosectors 44 and III] against the arrow I45. The feeding mechanism is nowfed by the sector 44 in the direction of the arrow 45 and, at the sametime, the rod I I8 is returned into the position shown in Fig. 2 fromthat shown in Fig. 5, and so is the blank holder. Two impressions arenow made by the fresh printing plate in the manner described.

In certain cases, for instance, if it is desired that in the secondimpression of a given printing plate on the blank 95 the second line ofthe printing plate should be at the side of the first line of its firstimpression in which case obviously the first line of the printing plateis not printed in the second impression: it is possible by displacingthe anchoring plate I3ll in the groove I3I from the central position inFig. 3, to place the second impression of each printing plate notexactly below the first impression but in staggered relation withrespect to the first impression in the longitudinal direction of theblank.

The graduation i3! and the index I36 serve for determining the amount ofdisplacement required for the anchoring plate I30.

Referring now to Fig. 6, it has been assumed that the anchoring plateI39 has been shifted to the right, as viewed in the feeding direction45, as far as it will go, and secured by the wing nut I33. With thisposition of the anchoring plate, when the rod H8 is shifted from theposition illustrated in Fig. 6 into that illustrated in Fig. 5 in thedirection of the arrow 57, Fig. 2, the blank holder moves into theposition shown in dot-anddash lines in Fig. 6 and the blank 95 isshifted to the left, against the arrow 45. When the anchoring plate I30is shifted to the right, the blank holder is moved in the oppositedirection, that is, with the arrow 45.
